Body of Evidence, by Patricia Cornwell

An audio book.

Kay Scarpetta is the Chief Medical Examiner for the State of Virginia. In this novel, Scarpetta is drawn into the case of the murder of a young novelist and her mentor. The setting is mostly the Richmond VA area, and some in Key West.

Good commuting entertainment.

The time setting is approximately late 80s. It's interesting to note the lack of cell phones, and the non-ubiquity of computers, although computers are used to some degree by the law enforcement agencies. The FBI is involved.
